UNITED STATES HENRY M. VAUGHAN, OF NEWTON, IOWA.

WASHING MACHINE.

Application filed December 21, 1922. Serial No. 608,291.

To all whom it may concern:

Be it known that I, HENRY M. VAUGHAN, a citizen of the United States of America, and a resident of Newton, Jasper county, Iowa, have invented certain new and useful Improvements in Washing Machines, of which the following is a specification.

My invention relates to improvements in washing machines, and the object of my improvement is to supply an oscillatory rubbing element within the tub of a washing machine provided with cleats which are undercut or grooved in such a mamier as to most effectively agitate the contents of the tub in the operation of the machine, thus more rapidly and thoroughly cleansing the contents.

This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which Fig. 1 is a perspective elevation of a washing machine tub equipped with my improved rubbing disk, the hinged cover and disk being in opened positions, but the operating mechanism for the disk being removed. Figs 2 and 3 are like under plan views of the cleated rubbing disk in slightly different arrangements of the cleats, and Fig. 4 is a cross section of one of the longitudinally and laterally grooved rubbing cleats. Fig. 5 is a section of part of said disk taken through one of the holes 2.

The washing machine tub 7, its hinged cover 8, the oscillatory rubbing disk 1 with its rock-shaft 9 traversing the cover 8 are of the usual type, and any appropriate or convenient mechanism or motive power therefor may be employed to rock the shaft 9 and disk 1, as may be desired.

The disk 1 may have a plurality of holes 2 to provide a ready circulation of water through the disk during the operation of the machine, but these are not essential to the special action upon the clothes contents of the tub of the depending rubbing cleats 3, 4 and 5 fixed on the lower face of said disk. The disk 1 may be of any other suitable con figuration and it as also the cleats may be of any desired size, relative arrangement and forms, while coming within the scope of my invention, which is the hollowing or undercutting or longitudinally and laterally grooving the cleats for the purpose hereinafter described.

My preferred relative arrangement or polongitudinally.

cured tothe disk 1" radially:

The grooving or hollowing of certain of the cleats may be along either side thereof As shown, each grooved cleat may have a cross-sectional form illustrated in Fig. 4, the cleat being an elongated rib, apically rounded, with a reentrant groove 6 extending along one side longitudinally.

As shown in Fig. 2, an ungrooved diametrical rib 3 may be positioned across the under face ofthe disk 1, and several shorter radial. and diametrically spaced grooved cleats or ribs 4 and 5 positioned at opposite sides of this rib or cleat 3. While the grooves 6 on the shorter radial cleats may open in the same direction, I have found the arrangement shown more eflicient, where the grooves 6 along one set of ribs 4 open oppositely to the grooves on the other set of ribs or cleats 5. This is because when the disk 1 is oscillated to and fro, the grooves 6 in one set of cleats 4L engage and rub the clothes more than the smooth sides thereof and agitate the water while moving in one direction, and when the disk is rocked back, the grooves 6 in the other cleats 5 reverse the rubbing and agitating effect upon the clothes and water in the tub quickly and with more cleansing effect upon the clothes and in causing better circulation of the water. The grooves receive and carry along portions of the Water and the clothes, thereby spreading and opening out the folds of the clothes and driving the soapy water through them with force.

As shown in Fig. 3, the diametrical cleat 3 is made in spaced alined sections, and the function of this diametrical cleat in either shape is to act as a barrier to prevent entangling of the clothes in the reversal of the disk, while better localizing the effect of the grooved walls ofthe particular cleats at one side of the cleat 3.

The dotted circles about and concentric with the holes 2 in the disk 1 indicate that the holes are of conical shape, with their smaller openings on the lower or cleat-beaning face of the disk. The conical holes afford quicker passage to water than the ordinary cylindrical holes.

Havingdescribed my invention, what I claim as new, and desire to secure by Letters Patent, is:

1. In a washing machine, a tub, an oscillasi'tioning of said cleats, is to have them seprojecting partsfwhich are grooved along one side only, the grooves on these "parts on one part of said body opening oppositelyto the like grooves onthe opposite part of body to engage the contents of the'tub When the body is rocked in either of opposite di rections. V

In a washlngmachine, a tub, an oscil- 10 latory" body po sitiojied therein, end radial cleats secured iipon said body, certain of said cleats being grooved along one side, and the said grooved cleats being segregated into groups in which the grooves in one group face oppositely from the grooves in another Signed at Newton, Iowa, this 25th day of November, 1922.
